1 PEDESTRIAN PASSAGEWAY Goal: Provide safe passageway for students to cross busy streets through Colorado College campus

2 OBJECTIVE Separate pedestrian-vehicle accident potential so as to minimally impact site s historic character and ensure student safety Provide a long term solution

3 OPTIONS CONSIDERED Temporary versus Permanent Existing at-grade crossings with beacons along Cascade has resulted in small number of student-vehicle accidents over past decade Current options considered [traffic calming to lane reduction] are temporary solution; they do not eliminate pedestrian-vehicle accident potential Rationale for options there have been past accidents, but it is not a big enough problem to warrant anything other that reducing vehicle speed or create choke point with single lane traffic Permanent solution pedestrian bridge or pedestrian underpass has been dismissed too quickly as viable option

4 PEDESTRIAN BRIDGE Permanent solution since it de-conflicts pedestrians and vehicles Could degrade historic character of the site unless carefully planned Needs to meet approval of local Historic Preservation Office & Colorado State Historical Preservation Office [SHPO]

5 PEDESTRIAN UNDERPASS Permanent solution because it de-conflicts pedestrian and vehicles Can permit traffic calming while not restricting traffic flow or causing traffic congestion Other concerns with underpass are: Student safety Drainage Historic character Constructability

6 STUDENT SAFETY Incorporate security system linked to campus police and security lighting Incorporate natural lighting in passageway design as accomplished in Unitah bridge design over Monument Creek

7 DRAINAGE Incorporate pump and underground storage for future use on campus and/or Incorporate lift pump system to channel water runoff to street drainage system

8 HISTORIC CHARACTER Incorporate architectural treatments into the design compatible with the historic content of the campus and surrounding area Treatments borrowed from historic structures on campus Include concrete paver walkways, cast stone elements, decorative balustrade walls, decorative fencing, ceramic tile, bronze hand railings

9 CONSTRUCTABILITY Small footprint approach using a compact structural design with traffic calming, but not impacting traffic flow Large footprint approach allowing easier access to passageway Designed to satisfy local Historic Preservation Office, SHPO and ADA standards Designed to accommodate small maintenance vehicular traffic safely

10 SMALL FOOTPRINT APPROACH Maintains 4-lane traffic flow Incorporate fence along median centerline Narrows median at passageway from 38 wide to 10 wide by moving both north and south bound lanes one lane toward the median centerline Permits use of outside lanes for ramp access to passageway Enhances traffic calming by slowing traffic at passageway location

11 SMALL AREA PLOT PLAN

12 LARGE FOOTPRINT APPROACH Maintains 4-lane traffic flow Incorporate fence along median centerline No change to existing median width Permits fan entry approaches [both sides of street], easing access to passageway Can protect existing large trees with islands in ramped fan entries [both sides of street]

13 EXAMPLES OF LARGE FOOTPRINT PLANS UCCS-North Nevada Shopping Passageway Briargate Blvd passageway in Cordera 30 TH Street passageway at Garden of Gods Visitor Center UC Bounder passageway

14 UCCS-NEVADA PASSAGEWAY

15 BRIARGATE BLVD PASSAGEWAY

16 GARDEN OF GODS PASSAGEWAY

17 UC BOULDER PASSAGEWAY

18 Summary Colorado College can solve the pedestrianvehicle conflict permanently with underground passageway: Without impacting the historic character of the surrounding communities Without restricting traffic flow destined to increase in the future
